L TED STATES LAURA EUGENIA DANIELS, OF FORT WORTH, TEXAS.

STEAM-COOKER.

To all whom it may concern:

Be it known that I, LAURA E. DANIELS, a citizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented certain new and useful Improvements in Steam-Cookers, ofwhich the following is a specification.

My invention relates to new and useful improvements in steam cookers.

Primarily the object of the invention is to improve a steam cooker setforth in Let ters Patent granted to me November 20th,

1906, and numbered 836,098 and August 25th, 1908, and numbered 896,898.

The novel features and particular improvements will be hereinafter fullypointed out.

With the above and other objects in view, the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in this specification and illustrated in theaccompanying drawings wherein:

Figure 1 is a vertical section of the cooker, Fig. 2 is a plan View,Fig. 3 is a detail in section of one of the receptacles and the coaotingcover, Fig. 4 is a vertical section showing a modified form of the coverand a different arrangement of receptacles, 5 is a horizontal sectionalview of the same, Fig. 6 is a vertical section of the style of cookershown in Fig. 1 and provided with cover clamps, Fig. 7 is a verticalsection of the form shown in Fig. 4 and provided with cover clamps, Fig.8 is a detail of one of the cover clamps in elevation, and Fig. 9 is adetail of the same in plan.

In the drawings the numeral 1 designates a boiler or jacket. This boileris formed of thin metal and is spun, stamped or pressed into shape so asto be formed without seams or sharp angles and to be light in weight topermit easy handling. At its upper end the boiler is flared or swelledoutward at 2 and terminates in an outwardly directed annular rolled bead3. A counter sunk cover 4 fits snugly into theflared portion 2 of theboiler and is provided with a lateral flange 5 projecting over the bead3. This cover is formed like the boiler and also of thin metal, havingno seam or sharp angle. The sides 6 of the cover are flared upwardly andoutward at substantially the same angle as the walls of the flaredportion 2 so as to lie firmly in contact therewith and thus form aSpecification of Letters Patent.

steam-tight joint. The frictional engagement of the cover with theboiler is sufli: cient under ordinary conditions to hold the former inplace. The cover is formed with a horizontal bottom 7 in which aplurality of openings surrounded by depending flanges 8, are provided.Each of these flanges is inclined downward as shown in Figs. 1 and 8, tosupport a food receptacle 9. The food receptacles are each formed from asingle piece of thin metal and without seams. Thegreater portion of eachreceptacle is gradually flared upward to a point where it is swelled ata greater angle as indicated at 10. Above this swelled portion the wallsof the receptacle are straight terminating in an outwardly directedannular rolled bead 11. In the upper end of each receptacle a countersunk lid 12 is adapted to fit snugly so as to form a steamtight oint.The side walls of each lid, the swelled portions 10 and the flanges 8are all inclined at substantially the same angle, so that eachreceptacle will have a tendency to wedge in its respective flange 8 andproduce a steam-tight joint, while the diameter of the lid of eachreceptacle is such as to cause the lid to wedge in the flange when thereceptacle is removed and the lid placed in the flange to close theopening and form a steam-tight joint.

I desire to call particular attention to the formation of the boiler 1,cover 4, lids 12 and receptacles 9. In each case the bottom is formedintegral with the sides, the intersection being slightly rounded toavoid a sharp angle and facilitate the formation of the part, at thesame time producing a more sanitary construction as sharp angles arediflicult to clean. Another feature of construction of great importanceis the absence of seams which would prevent the forming of steam-tightjoints. Another point to be observed is that where ever a steam-tightjoint is formed in this invention the contacting surfaces are broad soas to give a long bearing and the parts so shaped as to wedge.

The cooker can either be used as shown in Figs. 1 and 2 or as shown inFig. 6. As shown in Fig. 6, one or more of the receptacles 9 are removedand the opening in the cover 4 closed by fitting the lid of thereceptacle in the flange 8. This leaves one'or .more receptaclessuspended from the cover,

while within the boiler a perforated support its lid and withoutdisturbing the receptaoles within the boiler; while the receptacleswithin the boiler may be inspected by removing the lid from the flange 8of the cover and without disturbing the suspended receptacles. By thisarrangement more vessels may be used with the cooker.

In Figs. 4: 5 and 7 the receptacles and vessels are all placed on thesupport 13 within the boiler and a counter-sunk cover 15 like the cover1 with the exception of the flanged openings fitted on the boiler. Inthis form it is shown how a large vessel 16 can be placed on the supportand leave sufficient room for numerous other vessels and receptacles.

Where it is desired to use steam at a comparatively high pressure, it isnecessary to fasten the covers in place and if desired the lids of thereceptacles and vessels may also be fastened. Various kinds of fasteningdevices may be used and while I have. shown a particular form in thedrawings I do not wishto limit my invention to the same. The

fastening shown in the drawing comprises clamps 17, attached to oppositesides of the boiler or vessels. At its lower end each clamp is hinged at18 and provided at its upper end with a lug 19 prO ecting one way andthumb piece 20 extending in the opposite direction. When the clamps areswung up the lugs 19 engage over the flange of the lid or cover which isresilient enough to hold the part in place. A fastening of thischaracter is simple and eflicient and at the same time being attached tothe boiler or vessel can not be lost.

A steam cooker constructed in accordance with the invention herein setforth not only will be strong, durable and eflicient, but sanitary andcapable of many uses. It will further be compact and convenient andhaving comparatively few parts will not be likely to get out of workingorder.

In each of the covers a relief valve 21 is placed for the purpose ofrelieving the pressure of steam if the same should reach the dangerpoint.

What I claim is:

1. Theoombination in a steam cooker, of a cylindrical boiler having itsupper end inclined outward at an angle to the body, a counter-sunk coverhaving an upwardly and outwardly inclined side wall parallel to theinclined portion of the body and frictionally engaging therein, thecounter sunk cover having a plurality of openings and provided with downturned portions at the openings forming inwar'dly sloping flanges, aplurality of food receptacles, each having a swelled portion near itsupper end inclined outwardly directly from the body of the receptacle,the inclined swelled portion of each receptacle being parallel to theinclined flange of the cover and frictionally engaging therein, acounter-sunk cover frictionally engaging in each food receptacle abovethe swelled portion, and means for fastening the counter-sunk cover ofthe boiler to the boiler,

opening, each receptacle having a swelled portion below its upper endinclined acutely and directly from the body of the receptacle andfrictionally engaging in the inclined flange of one of the openings, theportion of the food receptacle above the swelled portion having avertical wall, and a countersunk lid frictionally engaging in thevertical wall portion of each food receptacle.

3. The combination in a steam cooker, of a cylindrical boiler, acounter-sunk cover fitting in the boiler and having a plurality ofopenings each surrounded by a depending inwardly sloped flange formedintegral with the cover, afood receptacle fitting in each opening, eachreceptacle having a swelled portion below its upper end inclined acutelyand directly from the body of the receptacle and frictionally engagingin the inclined flan e of one of the openings, the portion of the 00dreceptacle above the swelled portion having a vertical wall, acounter-sunk lid frictionally engaging in the vertical wall portion ofeach food receptacle, and each lid having a diameter. whereby it may befrictionally engaged in one of the flanges surrounding the openings ofthe cover.
